John,
matplotlib does have an interactive mode that can be turned on with a call
to plt.ion(). Note that any figure is spawned as a child thread. If you
run a script from the command line, the script won't end until the figure is
closed (hence you can't start another script).
However, another possible route is to design your code as functions that
take a figure or axes object, you could then just call the needed functions
for an existing axes object.
Another possibility (and maybe this is what you meant originally) is to have
a python or ipython session open and import the desired scripts in order to
execute them (with interactive mode turned on).
I hope this is helpful!
